F1 E interesting

[Dennis Toth]

Well after watching Monaco F1 and before the Indy 500 there was an Electric F1 race from Germany. This was all electric full F1 type cars. The interesting thing was they were reporting on the amount of battery capacity left for each car. The race was 33 laps on a road course with the pit stop coming at lap 19. By that point most had between 7-9% capacity left. For the pit stop they don't change the battery pack they change the whole car!! The other thing I found different was the tires had tread. At the end of the race many of the cars were down to 1% capacity with no loss of speed. However, the winner crossed the strip and within 1/2 lap it shut off completely. Interesting how much they can draw their packs down.

On to Coca-Cola 600.

Thanks to our troops.

Best,     DennisT

Interesting how much they can draw their packs down.

   No problem, if you don't care if you destroy them. I would bet they are "one-and-done" batteries, like the KERS batteries in the regular F1 cars (which are all hybrids).

   A big problem with the originals KERS system was that they were sometimes "3/4 and done"

It was like watching a silent movie about slow F1 cars with five gallon gas tanks.

More info:

For the first season, all teams were supplied an electric racing car built by Spark Racing Technology, called the Spark-Renault SRT 01E. The chassis was designed by Dallara, with an electric motor developed by McLaren (the same as that used in its P1 supercar), a battery system created by Williams F1 and a Hewland five-speed gearbox. Michelin will be the official tyre supplier.[6][7][8] For the first season, 42 electric cars have been ordered by the series, with four cars made available to each of the ten teams and two cars kept for testing purposes.[9]
